Strange as it may seem, humans seem to have evolved in a way that we have a need for external energy, such as energy from burning wood or fossil fuels. While the evidence is not 100% certain, it appears that we learned to use fire long enough ago that it is now necessary for our food to be cooked…There are other evolutionary deficiencies as well: How do we deal with our lack of fur? How do we deal with our evolutionary dental problems? How do we deal with “survival of the fittest”?…In this post, I will explain how these and other evolutionary issues relate to mankind’s need for external energy, such as wood, or gasoline, or electricity.
